SD 16:9 missing among CinGG BD-Render Video Formats
by Terje J. Hanssen 19 Jan '24

19 Jan '24

According to wikipedia, 16:9 SD video formats are also valid BD-Video formats https://en.wikipedia.org/wiki/Blu-ray#Video SD 720 × 480 29.97i 4:3 or 16:9[d] (anamorhic) 720 × 576 25i 4:3 or 16:9[d] The Create BD Format contains 720 x 576/ 25i/p and 720 x 480/ 29.97i/p Please verify if this these are SD 4:3 only? The wikipedia table lists only SD interlaced as valid SD BD-Video format If so, SD 16:9 interlaced are missing, while SD progressive are invalid?

according to my grep-fu this define not used anywhere, probably remnant from some cinelerra-cv era experiments in using ffmpeg for dv (today we can do the same directly) grep DV_USE_FFMPEG cinelerra/* grep: cinelerra/data: Это каталог cinelerra/filedv.h:#ifdef DV_USE_FFMPEG grep: cinelerra/i686: Это каталог grep: cinelerra/tests: Это каталог

mp2 audio profile

put in ffmpeg/audio may be you can change codec (second mp2) to libtwolame, different ffmpegs offer different versions when I query for mp2 encoder A..... mp2 MP2 (MPEG audio layer 2) A..... mp2fixed MP2 fixed point (MPEG audio layer 2) (codec mp2) A..... libtwolame libtwolame MP2 (MPEG audio layer 2) (codec mp2) from desktop (v 4.4.4) A....D mp2 MP2 (MPEG audio layer 2) A....D mp2fixed MP2 fixed point (MPEG audio layer 2) (codec mp2) from termux (v 6.1)

I just discovered this tool that aims to make backups on CD, DVD and BD discs safer. Any knowledge or experience with it? https://dvdisaster.jcea.es/ https://dvdisaster.jcea.es/misc.html#manual

mpeg2 hdv profile based on MLT profile
by Andrew Randrianasulu 16 Jan '24

16 Jan '24

attached just put where all other cinelerra-gg's video profiles live ... note, this is for progressive 25f 1080p HDV if you have mlt installed you can inspect other files usually in /usr/share/mlt-7/presets/consumer/avformat/hdv_* those profiles does not seem to carry interlacing info but I hope we for now carry it correctly ....

Anamorphic 16:9 SD Bluray
by Andrew Randrianasulu 16 Jan '24

16 Jan '24

so, it seems aspect_ratio not communicated currently correctly for this case but you can manually set aspect for ffmpeg video format to -> 1.77778/(720/576) = 1.42222 or SAR= DAR/PAR because ffmpeg really assumes we set SAR ! put aspect=1.42222 in additional codec options edit window. I'll think about how to automate it ....

Anamorphic 16:9 SD-DV(D) widescreen to AV1.webm
by Terje J. Hanssen 16 Jan '24

16 Jan '24

I wanted to test AV1.webm rendering from anamorphic 16:9 SD-DV(D) widescreen sources, which have different SAR 64:45 than 1080i HDV SAR 4:3 It would be fine to get this SAR value verified and clarified vs Wikipedia's table which specifies different for PAL (16:9) 720x576 : SAR 5:4, PAR 64:45 https://en.wikipedia.org/wiki/Pixel_aspect_ratio#Pixel_aspect_ratios_of_com… This legacy 16:9 SD format was created and can be obtained among the following methods:: 1. DV camcorders with Widescreen feature, the right/true way and wrong/fake way https://www.videouniversity.com/articles/dv-formats-everything-you-need-to-… 2. DV wide record or downconvert playback using a HD(V) camcorder with this feature 3. DVD video disc enhanced for 16:9 or a BD video disc with 16:9 SD content 4. Render/transcode i.e a HD(V) video file using a) Cin-GG b) FFmpeg I have used the two latter methods as follows: 4 a) Cin-GG Loaded a PAL 1080i/50 HDV clip Set Format Preset: PAL 576i (16:9) - DV(D) File Render File Format: FFmepg - avi (NB! because plain Raw DV still causes DAR 4:3) Audio: Preset: avi_pcm_s16.avi Video: Compression: dv_pal.avi ffprobe -hide_banner dv07_05_wide_cingg.avi Input #0, avi, from 'dv07_05_wide_cingg.avi': Metadata: software : Lavf60.16.100 Duration: 00:06:58.04, start: 0.000000, bitrate: 30342 kb/s Stream #0:0: Video: dvvideo (dvsd / 0x64737664), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 28802 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 48000 Hz, 2 channels, s16, 1536 kb/s mediainfo dv07_05_wide_cingg.avi General Complete name : dv07_05_wide_cingg.avi Format : AVI Format/Info : Audio Video Interleave Commercial name : DV Format profile : OpenDML Format settings : BitmapInfoHeader / PcmWaveformat File size : 1.48 GiB Duration : 6 min 58 s Overall bit rate mode : Constant Overall bit rate : 30.3 Mb/s Frame rate : 25.000 FPS Writing application : Lavf60.16.100 Video ID : 0 Format : DV Codec ID : dvsd Codec ID/Hint : Sony Duration : 6 min 58 s Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Bottom Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Stream size : 1.40 GiB (95%) Audio ID : 1 Format : PCM Format settings : Little / Signed Codec ID : 1 Duration : 6 min 58 s Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 76.6 MiB (5%) Alignment : Aligned on interleaves Interleave, duration : 208 ms (5.21 video frames) 4 b) FFmpeg transcode HDV to DV-wide ffmpeg -hide_banner -i hdv07_05.m2t -vf scale=720:576,setsar=64/45,setdar=16/9 -c:v dvvideo -c:a pcm_s16le dv07_05_wide.dv Stream mapping: Stream #0:0 -> #0:0 (mpeg2video (native) -> dvvideo (native)) Stream #0:1 -> #0:1 (mp2 (native) -> pcm_s16le (native)) Stream #0:0: Video: dvvideo, yuv420p(tv, bt709, top coded first (swapped)), 720x576 [SAR 64:45 DAR 16:9], q=2-31, 200 kb/s, 25 fps, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s frame=10457 fps=356 q=-0.0 Lsize= 1440422kB time=00:06:58.28 bitrate=28210.6kbits/s dup=217 drop=0 speed=14.3x ffprobe -hide_banner dv07_05_wide.dv [dv @ 0x56036476e580] Estimating duration from bitrate, this may be inaccurate Input #0, dv, from 'dv07_05_wide.dv': Metadata: timecode : 00:00:00:00 Duration: 00:06:49.72, start: 0.000000, bitrate: 28800 kb/s Stream #0:0: Video: dvvideo, yuv420p, 720x576 [SAR 64:45 DAR 16:9], 25000 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s mediainfo dv07_05_wide.dv General Complete name : dv07_05_wide.dv Format : DV Commercial name : DVCAM File size : 1.37 GiB Duration : 6 min 49 s Overall bit rate mode : Constant Overall bit rate : 28.8 Mb/s Frame rate : 25.000 FPS Recorded date : 1970-01-01 00:00:00.000 Video Format : DV Commercial name : DVCAM Duration : 6 min 49 s Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Time code of first frame : 00:00:00:00 Time code source : Subcode time code Stream size : 1.17 GiB (85%) Audio ID : 0 Format : PCM Format settings : Big / Signed Duration : 6 min 49 s Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 75.0 MiB (5%) --------------------------------- The HDV source has Scan order : Top Field First What would be right, Top or Bottom Field First for the output file (they differ)?

I tried again with commit 677df71d1663090d5a9ee3b1e48c3c17cb5cc8a2 from https://github.com/heroineworshiper/hvirtual it seems to link and work if I add two patches on top of it, attached (one git and one just plain diff) There was also problem libraw-1.2.0 - i just run libtoolize/autoreconf -f commands in this thirdparty directory

current set of my patches
by Andrew Randrianasulu 15 Jan '24

15 Jan '24

So, I tried to clarify a bit that we have display aspect ratio selectable, updated cingg team copyright year, added even more finegrained sar/dar reporting (guessed, container detected, codec detected). I tried to use libavutil function for reporting SAR in setformat.C but it need some dynamic gui subwindow/object, not static BCTitle... so just prototype that does not update as you update window, only calculated on window objects create time, so each time you reopen set format window. 3 new git diff patches hopefully for application 0003 should be applied on top of 0001-Add-guessed-detected-SAR-DAR-values-to-ffmpeg-asset-.patch from another thread one plain diff patch just for showing where SAR info might surface if I ever learn now to create dynamic text subwindows :)
